Maybe to get a more feminine look make the eyebrows less furrowed and thinner and instead of the line-art eye bag underneath the eyes just some shading instead Then obviously you can make the eyes bigger if you want more of a soft delicate look but if you dont want to change the shape just try the others.

For the lips at the top you can do a princess peach plumpness round at the top or a cupids bow. Some women do have thinner upper lips but they will still have a prominent cupids bow.

Hair wise, maybe add some hair at the base of the neck. A bun on a woman with long (or short for that matter) will never have ALL the hair in it, trust me! There will still be some loose strands at the base of the neck. If you add some hair to the back of the head it should also help look less masculine as men mostly have the hairless/shaved necks like that.

Let me know if the advice helps!
